I can only see that the block has a different color than the rest, this not necessarily means that it is made of iron i think.

ePER not shows cylinder sleeves/liners for the 1.4, that must mean it is an cast iron block i guess.
I wonder where the false information about the alloy crankcase comes from.
You can also find almost the same wrong text about the 1.4's in the Panda 100HP and Punto 95hp all over the internet.

good, op probable couldn't understand what the difference between cast iron a steel was either
you could have also got that same picture out of my gallery as i have just fitted one to my punto
wait a sec
the crank case is the sump extension, that bit is alloy, an that bolts onto the steel block
see like this
the t-jet has a forged crank up rated conrods an difrent pistons to the na 1.4 engines

The paint is a dead giveaway because iron is always painted as otherwise it goes pretty rusty on the outside. You can seen in the pics where there is no paint (around the core plugs etc) that its rusty. Defo cast iron.

The difference between cast iron and steel is all in the carbon content isn't it? I honestly thought most people would know the difference.
no if an op askes if its steel all they really want to know is is it the hard stuff or the soft stuff.
no need to complicate things for them with over technical stuff that they dont really need to be told.
pick a word they have already used makes it a lot easier for them
I drive a 5oo 1.4
It's OK for me , I only wish the throttle response would be better (even in sport-mode its quite
The dyno graph should look more like the one from the 1.2 , "lots" of torque downstairs and (almost) max. power from ~4500rpm to the limiter :yum:
16v engines need to be revved hard mate, the throttle goes all the way to the floor...
Throttle response is excellent - helped by close ratio gearbox
you need to keep it above 3500 rpm for the best power

Agreed. But I would slightly amend that to above 4,000 rpm for snappy throttle response and best power. Try the following - on a flat or slightly rising road, select 3rd gear (to load the engine properly) and floor the throttle at 2,000 rpm (Sport mode on, of course). Sit back and watch what happens. From 2,000 to 4,000 acceleration and engine response is roughly linear, but as the engine hits 4,000 it "comes on the cam" and really starts to take off. Power does not drop away until about 6,500 rpm. This is on my own, slightly modified I admit, 1.4 Sport. Also bear in mind that the engine ECU alters power delivery based on the speed with which the throttle potentiometer is opened, not just the throttle position. So slam it to the carpet
There is no point in driving the 1.4 at 3,000 rpm. You would have been better off with the diesel.

Well okay, I understand but I do think its better to give people correct information. It's not that technical really though to say the block is cast iron, the crankcase and head etc are aluminium alloy.
Interestingly I had a 1.4 Lounge courtesy car. I kind of feel compelled to say that the throttle response is not that sharp particularly even in sport mode. Well not compared to my 100hp. It's all relative I guess.
I'd agree you need to rev it hard, due to the weight of the 500.

Fiat stressed at initial launch that the 1.4 is in a very different state of tune to the Panda to reflect the target market for the car, which is I presume city runabout as opposed to back-road runabout
That would make a lot of sense as it really does feel very different.

It is a shame they did not keep the Panda state of tune for the Sport though..
then you have to say if it white or grey cast iron, then you have to explain what the diffrence is and so on....
when all they realy want to know was that it isnt alloy
Der Block is identisch mit den anderen 1.4 Blöcken. Der Unterschied zwischen dem Turbo- und dem Saugmotor sind die Kurbelwelle, die Pleulstangen (beide besseres Material) und Kolben, welche die Pleullager nach oben verschobem haben, um eine niedrigere Kompression zu erreichen.
Der Haupteil des Block is aus Gusseisen and ist verlängert mit dem Halbschalenträger für die fünf Kurbelwellenlager, welches aus Aluminium ist. Darunter ist die Ölwanne, welche aus Aluminium gefertigt ist.
Das Getriebe der Turbomotoren stammt vom Tipo mit dem Zweilitermotor.
